Effect of quality control program on surgical management in advanced ovarian cancer

Objective: We investigated the effect of our quality control (QC) program on the management strategy, completeness of the surgery, and clinical outcomes in advanced ovarian cancer. Methods: A retrospective review of medical records from January 2005 to December 2019 identified 129 patients with advanced ovarian cancer. Cases were categorized into group 1 (2005–2013) and group 2 (2014–2019) before and after implementation of the QC program. Comparisons included clinicopathological variables, operative details, recurrence and survival outcomes. Results: In Group 2 (n=44), after QC program implementation, primary debulking surgery (PDS) decreased (87.1% vs. 63.6%) and interval debulking surgery (IDS) increased (12.9% vs. 36.4%), indicating a shift in surgical strategy. Optimal resection rates improved significantly for PDS in group 2 (50.0% to 75.0%, p=0.007) and remained high for IDS in both groups (81.8% vs. 81.3%, p>0.999). Post-QC, advanced debulking procedures and co-operation with other departments increased in the IDS (p<0.05). Intra/post-operative complication rates were statistically comparable (p>0.05), whereas postoperative hospital stay was significantly shorter in group 2 (17 days vs. 22 days, p=0.001). Median recurrence-free survival increased after QC, although not statistically significant (19.18 months vs. 25.38 months, p=0.855). Conclusion: With QC program, treatment strategies and clinical outcomes were significantly improved in advanced ovarian cancer. Systematic QC monitoring program should be considered as routine surveillance for better surgical outcomes.
